Turn Discovery Into a Cited, Checkable Case Chronology
Evidence Copilot turns bodycam, jail calls, and scanned reports into timestamped transcripts and a grounded timeline your supervising attorney can verify in one click.
Why Timeline Work Drains Clerk Hours
- Manual case chronology building eats the trial calendar — Building a fact chronology in spreadsheets or on a whiteboard means re-reading police reports, scrubbing bodycam, and re-listening to jail calls every time new discovery drops. As case complexity rises — 28% of trial court attorneys cite increasing case complexity as a major source of delay — the final weeks before trial become a scramble to reconcile the exhibit list, the demonstrative timeline, and the theory of the case without a structured trial preparation checklist.
- Timeline facts without traceable sources are trial liabilities — A demonstrative timeline for trial must link every fact to its source document at a specific page or second — a police report page, a bodycam timestamp, a 911 call minute. Chronology spreadsheets and general project tools cannot carry citations, so clerks spend hours re-verifying facts that should take seconds, and report-vs-bodycam inconsistencies hide in the gap between the spreadsheet and the source.
- Scheduling pressure compresses the time you need for evidence review — Continuances and attorney scheduling conflicts disrupt preparation schedules — 48% of judiciary respondents cited attorney scheduling conflicts as a major source of delay. When your prep window shrinks, the first thing that slips is the careful side-by-side reading of reports against call audio and bodycam that a defensible case chronology requires.
Why Law Clerks <span class="gradient">Choose Evidence Copilot</span>
- Verify instead of re-watch — Verify instead of re-watch: every timeline event the AI agent suggests carries a citation that seeks the exact second of bodycam or page of the PDF. Spot-check one fact in a click instead of scrubbing 40 hours of footage, and keep the case chronology current as new discovery lands.
- Faster first-pass review — Faster first-pass review feeds your chronology: auto-signals on ingest compare every new file against earlier evidence in the case, surfacing report-vs-bodycam and statement-vs-call-audio inconsistencies as unreviewed signals before anyone asks. Flagged moments become timeline events and cross-exam prep material with both sides quoted.
- Defensible work product — Defensible work product for the exhibit list and timeline: nothing is auto-applied. AI-suggested redactions and multi-camera sync proposals file as suggestion cards marked 'needs review,' every action is audited, originals are immutable, and the exhibit pack export includes a MANIFEST.md citation index tying each exhibit to its source file.
What's included
- Word-level timestamps and speaker diarization mean a jail call or interrogation transcript you can cite line-by-line, with one-click speaker renaming that propagates across every segment.
- OCR turns scanned police reports and photo evidence — receipts, exhibits, screenshots — into searchable, citable text with bounding boxes kept for redaction.
- The AI evidence agent reads transcript windows, grabs video frames, extracts clips, and writes notes, timeline events, and tasks — every answer carries a clickable citation.
- Auto-signals compare each new file against earlier evidence in the case, surfacing candidate inconsistencies like report-vs-bodycam as unreviewed review signals.
- One-click case brief generates a grounded markdown overview with evidence inventory, key moments, inconsistencies, and follow-ups for your supervising attorney.
- Exhibit pack exports bundle video clips, still frames, and quoted excerpts with a MANIFEST.md citation index, gated by per-member export permission.
Quick wins
- Use the Miranda Timeline playbook to generate a chronological custodial-interrogation timeline with every event cited to the exact transcript moment — ready for the suppression motion outline.
- Build the exhibit list from real files with the Exhibit List Builder, then export the exhibit pack with its MANIFEST.md citation index so every demonstrative timeline fact traces back to a source.
How it works
- Upload the discovery dump — Drag in video, audio, images, and PDFs up to 2 GB by web upload — or forward attachments to the case's per-case inbound email address and let intake sort itself.
- Get transcripts and OCR text — Deepgram Nova transcription with speaker diarization and word-level timestamps, plus OCR for scanned reports and photo evidence, makes everything searchable and citable.
- Build the chronology and exhibits — Ask the AI evidence agent questions, save cited timeline events and notes, run the Exhibit List Builder, and export an exhibit pack with a MANIFEST.md citation index for attorney review.

What clients say
I used to rebuild the case chronology from scratch every time new discovery dropped. Now the timeline events carry citations into the exact second of bodycam, and my attorney can verify each one in a click instead of taking my word for it.
— Danielle Reyes
The OCR alone paid for itself — scanned reports with no text layer became searchable, citable text, and the Exhibit List Builder tied every draft exhibit to the actual file so our demonstrative timeline held up under scrutiny.
— Marcus Whitfield
Auto-signals flagged a statement-vs-jail-call inconsistency before I even finished my first pass. That's the kind of catch that used to take a full week of side-by-side reading — and it went straight onto the timeline with both quotes cited.
— Priya Raman
Frequently asked questions
How do I build a fact chronology for trial from bodycam and jail calls without re-watching everything?
Upload the media and Evidence Copilot returns word-level timestamped transcripts with speaker diarization. The AI evidence agent writes timeline events with citations into the exact video second, so you assemble the case chronology from cited moments instead of scrubbing footage. Every event is marked AI-generated and pending your review.
Can it handle scanned police reports and photo exhibits with no text layer?
Yes. OCR converts scanned PDFs and photo evidence — receipts, exhibits, screenshots — into searchable, citable text, with bounding boxes kept for redaction. That text feeds full-text search across transcripts and documents, so a fact buried in a 90-page scan is findable and citable.
What about exhibit numbering inconsistencies between prep and trial?
The Exhibit List Builder playbook drafts an exhibit list tied to the real files in the case, so numbering stays anchored to sources rather than ad-hoc spreadsheet labels. Exports go out as an exhibit pack with a MANIFEST.md citation index, and originals are never modified.
How long does it take to get a new case set up and transcribed?
Create a case, upload files up to 2 GB by web or email attachment, and transcription and OCR run on ingest — the Solo plan includes 15 media-processing hours per month and the Firm plan 60 with a priority queue. You can also email attachments to the case's inbound address and intake happens automatically.
How does this compare to stitching together Whisper and NotebookLM for discovery review?
The free DIY stack breaks at case scale: no diarization QC, no citations into source moments, no redaction workflow, and no audit trail. Evidence Copilot adds diarized transcripts, OCR, an AI agent whose answers cite the exact second or page, redaction with immutable originals, and audited exports — with published pricing starting at $39/user/mo and no feature tiers.
